OddSightSeer is a sports betting analytics tool. It is not a sportsbook.

• OddSightSeer compares odds across 20+ sportsbooks and the DFS apps (PrizePicks, Underdog, Pick6, Sleeper and Dabble) against a de-vigged fair line.
• A pick is +EV when a book's price beats the fair price; the fair line is shown next to every quote.
• Gold is $25/month with a 5-day free trial. Platinum is $40/month with a 7-day free trial.
• OddSightSeer is an analytics tool, not a sportsbook: it never takes bets or holds money.
• Gold is $25/month and covers straight bets. Platinum is $40/month and adds player props and the DFS apps. Both are month to month and can be cancelled any time.
• Both plans start with a free trial: 5 days on Gold and 7 days on Platinum. You add a card at checkout and it is not charged until the trial ends; cancel before then and you pay nothing.
• Sports covered: NFL, NBA, WNBA, MLB, NHL, college football and basketball, soccer (EPL, Champions League, Europa League, La Liga, Bundesliga, Serie A, Ligue 1, MLS, Liga MX), tennis, MMA and esports.

20 sportsbooks: DraftKings, FanDuel, BetMGM, Caesars, BetRivers, Hard Rock Bet, theScore Bet, Fanatics, betPARX, Bally Bet, Fliff, Bovada, BetOnline, MyBookie, LowVig, BetUS, ReBet, Pinnacle, ProphetX, Courtside.

3 exchanges: Novig, Kalshi, Polymarket — read from their own order books, with the dollars resting at the shown price.

5 DFS apps: PrizePicks, Underdog, Pick6, Sleeper, Dabble — every pick priced against the sportsbook market, with each app's payout table and multipliers applied.

That is 28 books on a Platinum board; Gold shows the 20 sportsbooks and 3 exchanges.

• Sportsbook prices come from The Odds API and refresh every few minutes; player props refresh every five.
• The exchanges (Novig, Kalshi and Polymarket) are read directly from their own order books, so the price shown is the ask you can actually hit, with the dollars resting at that price.
• The DFS apps (PrizePicks, Underdog, Pick6, Sleeper and Dabble) are read directly from each app, including Underdog's payout multipliers, Dabble's per-pick tags and Pick6's per-slate payout tables.
• Underdog's 4-pick flex pays 7.2x with all four correct and 1.4x with three, so each leg needs to hit 53.7% (-116) to break even.
• The fair line is a de-vig of every book's two-sided price (power method by default; multiplicative, additive and Shin are selectable), weighted toward Pinnacle, Novig and ProphetX.
• EV% is the fair probability times the decimal price, minus one. The stake shown is fractional Kelly on your bankroll, set once in Settings and used everywhere.

OddSightSeer does not accept wagers, hold funds, sell picks, or guarantee results. It is a research tool: it shows you the price, the fair price and the difference. Whether to bet is your call, and it should only ever be money you can afford to lose.
